Summary
Recurrent anterior and internal rotatory subluxation of the tibial plateau is a disabling symptom in patients with insufficiency of the anterior cruciate ligament.
Since 1970 we have used the N-test, a special jolt test to detect the characteristic instability. One hundred eighteen cases with anterior-internal rotatory instability of the knee seen at the Kanto Rosai Hospital and the University of Tokyo Hospital and diagnosed by arthroscopy and arthrotomy from 1973 to 1978 were reviewed. Most of the patients were athletes or sportsmen and the injuries commonly occurred in deceleration-injury mechanism and 81% of the cases were associated with meniscal tear.
Thirty-two cases were reconstructed by iliotibial tract transfer, twenty of whom had been evaluated from 1–5 years after operation. Postoperatively, giving-way incidents disappeared in eleven, markedly decreased in five, and were unchanged in four patients. The anterior and internal rotatory subluxation of the tibial plateau disappeared or decreased in seventeen and was unchanged in two cases.
Some type of defective anterior cruciate ligament was recognized in all our 118 cases and the capsular lesions were considered to play only a secondary role in exhibiting the instability.
Zusammenfassung
Die periodisch rezidivierende Subluxation des Tibiakopfes nach vorne and innen ist ein charakteristisches Syndrom bei Patienten mit einer Insuffizienz des vorderen Kreuzbandes. Um these Instabilitat ermitteln zu können, verwenden wir seit 1970 den sogenannten “N-Test”, eine von uns entwickelte Variante des “Pivot-shift”-Testes.
Im Kanto Rosai Hospital und in der Universitätsklinik Tokio konnten von 1973–1978 118 Fälle mit dieser Instabilitat untersucht and durch Arthroskopie und Arthrotomie diagnostisch gesichert werden. Die Mehrzahl der Patienten waren Sportler, bei denen es bei Decelerationsmechanismen zum Unfall kam. In 81% der Fälle lag gleichzeitig ein Meniskusriß vor. Von 32 durch Verlagerung des Tractus iliotibialis behandelten Patienten werden 20 1–5 Jahre post operationem nachuntersucht. In 11 Fällen verschwand das „giving-way”, das unsichere, plötzliche Nachgeben im Knie vollständig; in 5 Fällen nahm es deutlich ab und nur 4mal blieb es unverändert. In 17 Fällen verschwand oder verringerte sich die Rotationssubluxation nach vorne and innen und nur in 2 Fällen trat keine Veränderung ein. Ein Defekt des vorderen Kreuzbandes wurde in all unseren 118 Fällen festgestellt wohingegen Kapselverletzungen beim Zustandekommen der Instabilität als zweitrangig angesehen werden.
